Chapter 5Tissues
TissuesCells are arranged in ____________________________
that provide specific functions for the bodyCells of different tissues are
_________________________________ differently, which leads to their differences in _____________________________.
The Tissues of the body include four major types: Epithelial ______________________________________ Muscular Nervous
Epithelial TissuesWidespread throughout the body – Covers
________________________________ and lines body surfacesAnchored to a ____________________________ membraneMade up of tightly packed cells containing little
intercellular materialGenerally lack ______________________________________Are frequently replacedFunction in protection, secretion, absorption,
excretion and sensory reception.There are 9 types of Epithelial Tissues
Structure of Epithelial Tissues
Simple Squamous Epithelium
Made up of a ____________________ layer of thin, flattened cells
Functions in the exchange of
___________________ in the lungsLines blood and
lymph vessels as well as body cavities
Simple Cuboidal Epithelium
Consists of a single layer of ___________________-shaped cells with centrally located nuclei
Functions in ____________________ and absorption in the kidneys and in secretion in glands
Simple Columnar Epithelium
Made up of rows of
_________________________ cells whose nuclei are all located near the basement membraneLines the ______________,
stomach and intestines where it protects underlying tissues, secretes digestive fluids and absorbs nutrients
In the intestine, these cells possess _____________________ that increase the surface area available for absorption.
Pseudostratified Columnar Epithelium
Appeared ______________________ due to the varying positions of their nuclei within the rows of cells, but are not truly layered.
________________ may be present
Cilia on these cells aid in moving eggs through oviducts to the uterus in the female reproductive system
Stratified Squamous Epithelium
Made up of _______________
of ___________________ cells that are designed to protect underlying layersMakes up the outer
layer of skinLines the
________________, throat, vagina and anal canal
Stratified Cuboidal Epithelium
Consists of two to three layers of ___________________________
cells lining a _________________ (opening) of the mammary glands, sweat glands and pancreas.Several layers of cells
provide greater protection than a single layer.
Stratified Columnar Epithelium
Consists of several layers of cells
Found in part of the male
_______________ and parts of the pharynx
Transitional EpitheliumDesigned to _________________________ and return to its
normal sizeFound in the urinary bladder
Design provides distensibility (_________________________) and keeps urine from diffusing back into the internal cavity
Glandular EpitheliumMade up of cells designed to produce and secrete
substances into _________________________ or into body fluids___________________________ glands – glands that
secrete products into ducts___________________________ glands – glands that
secrete products directly into body fluids and blood.
Glandular Epithelium
Connective Tissues
Bind, support, protect, serve as __________________________________, fill spaces, store fat, produce blood cells, protect against infection and repair tissue damage
Unlike epithelial tissues, connective tissues have abundant _________________________________ material and have good blood supplies (except in cartilage)
There are 6 types of connective tissues
Loose Connective Tissue
Forms delicate, thin ___________________________ throughout the body that bind body parts together.
Binds the skin to underlying __________________________ and fills spaces within muscle.
Adipose Tissue
Designed to store ________________
Found beneath the skin, around joints, padding the
_________________________ and other internal organs, and in certain abdominal membranes.
Dense Connective Tissue
Consists of densely packed ____________________ and is very strong, but lacks a good blood supply.
Is found as part of
___________________ and ligaments
CartilageProvides a supportive framework for various
structures._______________________________ Cartilage – is white with
abundant fine collagen fibersIs found at the end of bones and supports respiratory
passages
__________________________________ Cartilage Provides a framework for the external ears and parts of
the larynx
_____________________________________________Tough tissue that provides a shock-absorbing function
in intervertebral disks and in the knees and pelvic girdle
Cartilage
BoneThe most rigid
_________________________ tissue
Bone cells are called
_________________________Has a good blood
supply, enabling rapid recovery after an injury.
BloodComposed of red and
white cells suspended in ____________________________
Formed in the red bone _______________________
Functions to transport substances throughout the body.
Muscular Tissue
Muscle cells or fibers can ______________________
Muscular tissue consists of three main types:__________________________________
__________________________________
__________________________________
Skeletal Muscle TissueAttached to
______________________________________________ –
can be controlled by conscious effort
Cells (muscle fibers) are long and cylindrical, ______________________ (striped) and have many nuclei
Contract from nervous impulse and then relaxes
Smooth Muscle TissueLacks ___________________________,
only has one nucleus, and consists of spindle shaped cells
___________________________ – is not controlled consciously
Found in the walls of internal _____________________________ and in the digestive tract, blood vessels and urinary bladder
Cardiac Muscle TissueFound only in the
____________________Consists of
branching ____________________ that are connected to each other
Has a single nucleus in each cell, but appears stretched
Nervous TissueFound in the
___________________, spinal cord and nerves
Neurons or nerve cells conduct nervous ____________________
____________________ (helper cells) support and nourish the neurons
